Optoplex Corporation, a leading supplier of innovative fiber-optic components for the next-generation communication systems, announces that its DQPSK demodulator and QPSK mixer, both designed for 100-Gb/s systems, have successfully completed sample evaluations by development groups at several major telecom systems providers.

While 40-Gb/s system market is slowly taking off, major network operators are already evaluating and making plans for 100-Gb/s optical transmission equipment, and anticipating roll-out in 2010. Light Reading is seeing a push to 100-Gb/s as service providers build out capacity to handle the growing demands for more services, such as video and enterprise-class services.

Optoplex’s engineering team has already started working with its key customers in providing the state-of-the-art DQPSK demodulators and QPSK mixers. Depending on the architecture, either the purely phase-based DQPSK scheme or the polarization- and phase-diversified QPSK scheme is one of the leading candidates of modulation format to be adapted by 100G systems. Both devices are free-space optics- based phased interferometers and are extension of Optoplex’s DPSK demodulator platform. These components are athermal, compact in size and designed for manufacturability.

During next week’s Optical Fiber Communication Conference and Exposition (OFC) in San Diego, CA, Optoplex (Booth# 2642) welcomes designers of optical transport systems and subsystems to view its innovative product portfolio, and discuss their needs in making their choices of 100-Gb/s components.

Optoplex provides customized solutions to telecom network equipment and testing instrument providers for wavelength routing and signal conditioning. Current product families include DPSK demodulator/Delay line interferometer (DLI), DQPSK demodulator, 90-degree optical hybrid, Optical interleaver, Tunable optical filter / Reconfigurable optical add/drop multiplexer (ROADM), Optical performance monitor (OPM) / Optical channel monitor (OCM).
